PLEASE no envelopes as a choice

I've just submitted my Christmas card, which is a 5x7 folded card plus a 5x7 flat card. I only need the one set of envelopes, to mail the two pieces together. 

There is NO option to request NO ENVELOPES as an envelope option. I get four choices, but NOT getting enveloped isn't one of the options. 

Please consider this for future upgrades.

Thanks!
